Abstract
Background The increased and accelerating utilization of 3D printing in medicine opens up questions regarding safety and efficacy in the use of medical models. The authors recognize an important shift towards point-of-care manufacturing for medical models in a hospital environment. This change, and the role of the radiologist as a central facilitator of these services, opens discussion about topics ranging from clinical uses to patient safety to regulatory implications. Results This project first defines three groups of patients for whom 3D printing positively impacts patient care. The steps needed for each group are described. Conclusions We provide our opinions regarding the regulatory role that we feel is most appropriate, balancing safety and efficacy with the autonomy of individuals in the field to make the greatest positive impact on healthcare.

Abstract
SETTING The emergence of multidrug-resistant tuberculosis (MDR-TB) threatens the ongoing control of tuberculosis (TB). The Australian state of New South Wales (NSW) has low TB and MDR-TB incidence. OBJECTIVE To examine the epidemiology and the clinical and public health management of MDR-TB in NSW. DESIGN A retrospective case-series analysis of MDR-TB diagnosed in NSW between 1999 and 2010 was undertaken. A standardised questionnaire was used to collect information from the public health surveillance system, medical records and the State Mycobacterium Reference Laboratory about clinical features, drug susceptibility, treatment regimens, hospitalisation, risk factors for tuberculous infection, contact tracing and patient outcomes. RESULTS Fifty-five cases of culture-confirmed MDR-TB, including two cases of extensively drug-resistant TB, were diagnosed. All cases were reviewed by an expert management panel. Fifty cases (91%) were foreign-born, and 50 cases (91%) had fully supervised treatment. Of the 55 cases, 46 (84%) successfully completed treatment, 3 (5%) died of TB and 3 (5%) required surgery. No MDR-TB cases were reported among contacts. CONCLUSION Using a multidisciplinary, expert guided, case-management approach, the NSW TB Control Program achieved excellent MDR-TB outcomes. The impact of global increases in MDR-TB requires sustained commitment to TB in all settings.

Abstract
Clinically relevant diagnosis of human bocavirus 1 (HBoV1) is challenging, as the virus is frequently detected in asymptomatic patients, and cofindings with other respiratory viruses are common. The clinical value of current diagnostic methods, such as PCR, is therefore low, and alternative diagnostic strategies are needed. We describe for the first time the use of an antigen detection assay for the rapid identification of HBoV1 in a paediatric patient with respiratory tract infection symptoms. We estimate the duration of active HBoV1 infection to be 6 days.

Abstract
BACKGROUND Calcinosis is a disabling, rarely discussed manifestation of systemic sclerosis (SSc) for which the natural history and management is understood poorly. OBJECTIVES To develop a calcinosis specific patient reported outcome measure (PROM) that can be used for future clinical research to test the effects of therapy on scleroderma related calcinosis. METHODS Patients were selected for participation by their scleroderma physicians. Four focus groups and individual interviews were recorded and transcribed verbatim. Patients were asked to frame questions to help a physician learn if calcinosis was better, worse or the same. Patient transcripts underwent an iterative inductive process (no preconceived coding, content drives coding and analysis) by at least five independent analysts including at least one research team member with SSc. Concepts were triangulated to identify a comprehensive set of meaningful concepts with occurrence quantified per participant. RESULTS Twenty-three patients (22/23 female, 19/23 white, with mean disease duration 14.8 years) consented and were interviewed. Responses included concepts of self-management strategies and recurrent hypotheses relating calcinosis development to trauma, Raynaud's and cold exposure. We identified discrete concepts such as the perceived association between cold exposure, Raynaud's and calcinosis severity. Calcinosis tended to present along with or soon after SSc diagnosis and remained throughout disease duration - though was not yet compared to report of first Raynaud experience. CONCLUSIONS Patient observations and self-management behavior provide opportunities for experts to learn from and to preemptively educate physicians and patients. Patients are eager for self-management guidance. These concepts are the groundwork for PROM development. However, patients suggested a composite of scales anchored in pain, size, frequency, number and related impairment may reasonably serve as an interim instrument for SSc calcinosis.

Abstract
Background The frequency of acute large vessel occlusions in relation to clinical severity has not yet been established in a comprehensive, consecutive and unselected cohort of patients with hyper-acute cerebral ischemia. Aim The aim of this study was to establish the frequency of acute large vessel occlusions and describe the relations to the National Institutes of Health Stroke Scale (NIHSS), lesion site and time from symptom onset in unselected consecutive patients with hyper-acute cerebral ischemia. Methods A prospective single hospital registry was based on consecutive unselected patients admitted from July 2009 to December 2011 with symptoms of acute cerebral ischemia within 4·5 h from symptom onset. ICA, M1, M2, ACA, PCA, BA and VA were assed for occlusions. Best NIHSS-cut-off values were calculated based on sensitivity and specificity for detecting any, anterior and posterior occlusions and the effect of time after symptom onset was assessed. Results Six hundred thirty-seven patients, with admission NIHSS: 1–42, were included; 183 patients presented with acute vessel occlusions (28·7%) in 15 different combinations of occlusions. The best NIHSS-cut-off for detecting any occlusion was 6. NIHSS is highly depending on lesion site, highest values being observed in relation to combined and M1 occlusions. Conclusion Acute vessel occlusions are frequent in unselected patients. Occlusions occurred in all NIHSS score values but a NIHSS cut-off value of 6 most optimally predicted acute vessel occlusion, even though accuracy was low.

Abstract
The ultimate goal of government health systems is to provide highly effective equitable services that save lives and reduce morbidity and mortality. The pressure to conform to duplicative global and donor initiatives compounds existing challenges to health systems strengthening such as shortages of human resources for health, weak supply chains, inadequate laboratory services and parallel data management systems. This article illustrates how primary health care, as the point of entry into the health care system for the majority of individuals in sub-Saharan Africa, should be strengthened to ensure that individuals and their communities receive essential, holistic care.

Abstract
BACKGROUND The human face and body are rich sources of socio-emotional cues. Accurate recognition of these cues is central to adaptive social functioning. Past studies indicate that individuals with schizophrenia (SZ) show deficits in the perception of emotion from facial cues but the contribution of bodily cues to social perception in schizophrenia is undetermined. The present study examined the detection of social cues from human gait patterns presented by computer-generated volumetric walking figures. METHOD A total of 22 SZ and 20 age-matched healthy control participants (CO) viewed 1 s movies of a 'digital' walker's gait and subsequently made a forced-choice decision on the emotional state (angry or happy) or the gender of the walker presented at three intensity levels. Overall sensitivity to the social cues and bias were computed. For SZ, symptom severity was assessed. RESULTS SZ were less sensitive than CO on both emotion and gender discrimination, regardless of intensity. While impaired overall, greater signal intensity did improve performance of SZ. Neither group differed in their response bias in either condition. The discrimination sensitivity of SZ was unrelated to their social functioning or symptoms but a bias toward perceiving gait as happy was associated with better social functioning. CONCLUSIONS These results suggest that SZ are impaired in extracting social information from gait but SZ benefited from increased signal intensity of social cues. Inaccurate perception of social cues in others may hinder adequate preparation for social interactions.

Abstract
Introduction Vascular pathology in the extracranial vertebral arteries remains among the possible causes in cryptogenic stroke. However, the diagnosis is challenged by the great variety in the anatomy of the vertebral arteries, clinical symptoms and difficulties in the radiological assessments. The aim of this study was to assess the prevalence of CT angiography (CTA)-detected pathological findings in the extracranial vertebral arteries in an acute stroke population and secondly to determine the frequency of posterior pathology as probable cause in patients with otherwise cryptogenic stroke. Method The analysis was based on 657 consecutive patients with symptoms of acute stroke and a final diagnosis of ischemic stroke or transient ischemic attack. On admission, a noncontrast CT cerebrum and CTA were performed. A senior consultant neuroradiologist, blinded to clinical data, reviewed all CTA scans systematically, assessing the four segments of the extracranial vertebral arteries. First, the frequency of pathological findings including stenosis, plaques, dissection, kinked artery and coiling was assessed. Subsequently, we explored the extent of the pathological findings that were the most plausible causes of stroke, namely either a possible dissection or a kinked artery. Results Findings in the extracranial vertebral arteries included significant stenosis (0.8%), atherosclerotic plaque types (3.8%), possible dissections (2.6%), kinked arteries (2.6%) and coiling (32.0%). Eighteen patients (2.8%) with pathological findings had an unknown cause of stroke, likely posterior symptoms and no clinical stroke symptoms from the anterior circuit. Of these, 3 cases were kinked arteries (0.5%) and 15 cases (2.3%) were possible dissections. Conclusion We found that in approximately 3% of the study population, the most plausible cause of the cryptogenic strokes was due to a pathological finding in the posterior extracranial vertebral arteries, being either a possible dissection or a kinked artery. In general, posterior vascular pathology is not uncommon, and CTA is a useful modality in the detection of changes based on characteristics and locations of findings in the extracranial vertebral arteries. Ultrasound examination can be a useful supplementary tool in deciding the consequence of vascular findings on CTA.

Abstract
Easy-to-perform and valid assessment scales for the effect of thrombolysis are essential in hyperacute stroke settings. Because of this we performed an external validation of the DRAGON scale proposed by Strbian et al. in a Danish cohort. All patients treated with intravenous recombinant plasminogen activator between 2009 and 2011 were included. Upon admission all patients underwent physical and neurological examination using the National Institutes of Health Stroke Scale along with non-contrast CT scans and CT angiography. Patients were followed up through the Outpatient Clinic and their modified Rankin Scale (mRS) was assessed after 3 months. Three hundred and three patients were included in the analysis. The DRAGON scale proved to have a good discriminative ability for predicting highly unfavourable outcome (mRS 5-6) (area under the curve-receiver operating characteristic [AUC-ROC]: 0.89; 95% confidence interval [CI] 0.81-0.96; p<0.001) and good outcome (mRS 0-2) (AUC-ROC: 0.79; 95% CI 0.73-0.85; p<0.001). When only patients with M1 occlusions were selected the DRAGON scale provided good discriminative capability (AUC-ROC: 0.89; 95% CI 0.78-1.0; p=0.003) for highly unfavourable outcome. We confirmed the validity of the DRAGON scale in predicting outcome after thrombolysis treatment.

Abstract
BACKGROUND AND AIM Significant tumour progression was observed during waiting time for treatment of head and neck cancer. To reduce waiting times, a Danish national policy of fast track accelerated clinical pathways was introduced in 2007. This study describes changes in waiting time and the potential influence of fast track by comparing waiting times in 2010 to 2002 and 1992. METHODS Charts of all new patients diagnosed with squamous cell carcinoma of the oral cavity, pharynx and larynx at the five Danish head and neck oncology centres from January to April 2010 (n=253) were reviewed and compared to similar data from 2002 (n=211) and 1992 (n=168). RESULTS The median time to diagnosis was 13 days (2010) versus 17 days (2002; p<0.001) and 20 days (1992; p<0.001). Median days from diagnosis to treatment start were 25 (2010) versus 47 (2002; p<0.001) and 31 (1992; p<0.001). Total pre-treatment time was median 41 days in 2010 versus 69 days (2002) (p<0.001) and 50 days (1992; p<0.001). Significantly more diagnostic imaging was done in 2010 compared to 2002 and 1992. When compared to current fast track standards the adherence to diagnosis improved slightly from 47% (1992) to 51% (2002) and 64% (2010); waiting time for radiotherapy was within standards for 7%, 1% and 22% of cases, respectively; waiting time for surgery was within standards for 17%, 22% and 48%, respectively. CONCLUSION The study showed a significant reduction in delay of diagnosis and treatment of head and neck cancer in 2010, but still less than half of all patients start treatment within the current standards.

Abstract
Reproduction is an event that requires the coordination of peripheral organs with the nervous system to ensure that the internal and external environments are optimal for successful procreation of the species. This is accomplished by the hypothalamic-pituitary-gonadal axis that coordinates reproductive behavior with ovulation. The primary signal from the central nervous system is gonadotropin-releasing hormone (GnRH), which modulates the activity of anterior pituitary gonadotropes regulating follicle stimulating hormone (FSH) and luteinizing hormone (LH) release. As ovarian follicles develop they release estradiol, which negatively regulates further release of GnRH and FSH. As estradiol concentrations peak they trigger the surge release of GnRH, which leads to LH release inducing ovulation. Release of GnRH within the central nervous system helps modulate reproductive behaviors providing a node at which control of reproduction is regulated. To address these issues, this review focuses on several critical questions. How is the HPG axis regulated in species with different reproductive strategies? What internal and external conditions modulate the synthesis and release of GnRH? How does GnRH modulate reproductive behavior within the hypothalamus? How does disease shift the activity of the HPG axis?

Abstract
Five children referred to a child-family intervention program wore a radio transmitter in the home during pre-intervention and termination assessments. The transmitter broadcast to a receiver-recording apparatus in the home (either activated by an interval timer at predetermined "random" times or by parents at predetermined "picked" times). "Picked" times were parent-selected situations during which problems typically occurred (e.g., bedtime). Parents activated the recorder regularly whether or not problems occurred. Child-deviant, parent-negative, and parent-commanding behaviors were significantly higher at the picked times during pretest than at random times. At posttest, behaviors in all three classes were substantially reduced at picked times, but not at random times. For individual subject data, reductions occurred in at least two of the three dependent variables for three of the five cases during random time assessments. In general, the behavioral outcome data corresponded to parent-attitude reports and parent-collected observation data.
